Hello Farhan.Afzal.

1) You should know about your motherboard model name(You can know this by the 3DP Chip. But it may not do so exactly.).

2) You can be download(BIOS ROM file & updater) from website of your motherboard provider.

3) To run the updater. And select the BIOS ROM file.

3DP Chip give no BIOS. Because BIOS update can be dangerous to computer.

Thanks for using 3DP Software.
